Question

IF THE SURFACE AREA OF A SPHERE IS 616 cm ^2, THEN FIND IT'S RADIUS !!! PLZ FAST !!!!

Answer 1

Surface area 4πr^2
1/2√A/√π

Answer 2

surface area of sphere = 4pie r^2.
$616 = 4\pi {r}^{2}$
$\pi {r}^{2} = \frac{616}{4}$
value of pie =22/7.
${r}^{2} = \frac{616 \times 7}{4 \times 22}$
${r}^{2} = \frac{4312}{88}$
${r}^{2} = 49$
$r = \sqrt{49} = 7$
therefore r= 7

it's best answer and correct also.
I'm sure please mark it as brainlist.
